WOOD-PLANING MACHINE.

SPECIFICATION forming part of Letters Patent No. 324,056, dated August 11, 1885.

(No model.)

To all whom it may concern.-

Be itknown that we, JAMES F. WELGH, ALFRED B. HUTCHINSON, and WILLIAM H. GRAY, all of Green Point, in the city of Brooklyn and county of Kings and State of New York, have invented a new and useful Improvement in Wood-Planing Machines, of which the following is a specification.

In wood-planing machines in which the under cutter-head is near the delivery end of the machine the cutter-head is arranged between and below two parallel bars or plates, which form between them a mouth for the cutter-head, and over which the lumber passes.

1 These bars or plates are adjustable vertically to vary the projection of the cutters above them, and above the cutter-head and bars or plates is a top platen or pressenbar, which holds the lumber to the cutters, while just beyond the cutter-head and at the delivery end of the machine is a table over which the lumber is delivered, and which is mounted upon and above the end girth of the machine.

Our invention consists in novel combinations of some or all of the parts above described, whereby greater facility is afforded for getting at the lower cutter-head for sharpenin g cutters or for adjusting, beading, or rabbeting irons or other cutters.

In the accompanying drawings, Figure l is a partial elevation of the delivery end of a planing-machine embodying our invention, the presser or top platen being represented in dotted lines as swung upward and outward to one side'of the machine. Fig. 2 is a sec tion on the plane of the dotted linear m, Fig. 1. Fig. 3 is a plan of a portion of the delivery end of the machine. Fig. 4 is a side elevation of the portion of the machine shown in Fig. 3, the cutter-shaft or journal only being in section. Fig. 5 is an elevation on a larger scale of one of the two bars which form the mouthpiece for the under cutter-head and a holderwherein said bar is supported; and Fig. 6 is a plan of the parts shown in Fig. 5.

Similar letters of reference designate corresponding parts in all the figures.

A A designate parts of the two side frames of the machine, and B designates the lowercutter-head the journals 1) of which are fitted to bearings in boxes C, and have upon them pulleys b for the reception of driving-belts.

The boxes C are fitted to slideways 0, secured to the frames A, and by means of adjustingscrews 0 and binding or tightening screws 0 the boxes and cutter-head may be adjusted vertically and held in place after adjustment.

A designates the cross or end girth which connects the side frames, A. Itis at one end pivoted to bearers a. on one side frame, A, and its opposite end is detachably connected with the other side frame by a bolt or pin, a. When the bolt or pin a is removed, the girth, A can be swung on its pivotal point a and outward into the position shown by dotted lines in Fig. 3. The girth A carries a table, I), which is supported upon its top, and at one end, d, is pivoted to the girth, while at its other end it is detachably connected therewith. The means forming this detachable connection consists, as here shown, of a slot or notch, 01, in the free end of the table, which is adapted to swing onto or receive a pin or stud, (F, on the girth, and a cross-pin or screw, d, which is then inserted across the slot or notch, as shown best in Fig. 3. By taking out the b'oltor pin a. the girth may be swung outward, bearing the table upon it, and by removing the screw or looking-pin d the table maybe swung outward alone, leaving the girth stationary. On the opposite sides of and slightly above the cutterhead B are bars or plates E E, above the latter of which the cutters project sufficiently to make the cut, and over which the lumber passes.

The bar E is adjustable upward and downward independently of the cutter-head. The bar E is supported by a cross-bar or stretcher, E", which is bolted at its. ends 6 to brackets upon the side frames, A, as shown in Fig. 3. The ends 0 of the bar E are fitted to pockets or housings e on the bar E and are capable of adjustment upward and downward therein by screws 0. The bar E has its ends 6 fitted in a similar manner to pockets 6 formed upon a bar-holder or stock, E, which extends across parallel with the bar The ends 0 of the end of the barholder is adjust-ably secured by a bolt, 0*, passing through a slot, 0", transverse to the length of the bar-holder. This plate or piece E is pivoted at c to a bracket, 0 projecting from the box 0, which is at the left hand of Fig. 3, and may be considered a part of the barholder E The opposite end of the barholdcr is detachably connected with the box (3 at the right-hand side of Fig. 3. As here shown this connection is formed by a slot or notch, 0 in the end of the bar-holder, engaging with a stud or bolt, 0 fixed in a bracket, 0 cast upon the box G, which is at the right hand of Fig. 3.

By loosening the screw 0 the bar-holder E may be adjusted bodily outward and inward ielatively to the cutterhead and into parallelism therewith, and the screw 0 being afterward tightened, the bar-holder may be swung o upon the pivot c outward into the position shown by dotted lines in Fig. 3. 1 designates the top platen or presser, which is adjustable upward and downward in a frame or holder, F by means of screws], one at each end op eratcd from a common shaft, f, connected by bevel or other gearing with the screws f.

The boxes 0 have pairs of upwardly-projcctin g bearers or lugs f through which pass bolts f and the frame or holder F of the presser F has at its ends notches or slots f which, when the presser and frame are in the position shown by full lines in Fig. 1, rest upon and are supported by the bolts f The frame F is securely fastened to the boxes 0 to prevent its lifting by means of bolts f which have their heads bored to fit the bolts f between the notches or slots f of each pair. The frame F has at opposite ends outwardlyslotted earsf, which receive the bolts f and by loosening the nut of either bolt] and swinging it outward to free it from its slotted earf the frame F may be swung upward on its opposite end, at which the bolt f forms a pivot. By swinging upward the presser or top platen and its frame F F, and by swinging outward the girth A and table 1) and the barholder and bar E E, ready access is afforded to the cutterhead B for sharpening and adjusting or removing and replacing cutters and beading or rabbetin g irons.

We are aware that it is not new to arrange a top platen or presser so that it may be swung upward on a pivot at its end to expose the under cutter-head, and we are also aware that it is not new to pivot an end girth or a table at its one end to provide for swinging it outward. \Ve do not therefore claim these features, broadly, as of our own invention.

hat we claim as our invention, and desire to secure by Letters Patent, is

1. The combination, with the under cutterhead, its boxes and side frames, and a presser above the cutter-head, of an end girth piv- 5 oted at one end to swing outward, and a bar or mouthpieceindependent of the swinging girth and presser and supported by the cutterhead boxes, substantially as herein described.

, 2. The combination, with the under cutterhead, its boxes and side frames, and a presser above .the cutterhead, of an end girth pivoted at one end to swing outward, a table movable with and pivoted to the girth so as to swing independent thereof, and a bar or mouth piece independent of the swinging girth, table, and presser and supported by the cutter-head boxes, substantially as herein described.

3. The combination, with the under cut-terhead and its boxes, of a bar-holder pivoted to one box to swing outward, and having a detachable connection with the other box, and a bar or mouth-piece adjustable in and carried by the swinging bar-holder, substantially as herein described.

4. The combination, with the lower cutter head and its boxes (3, of the bar-holderE' constructed with pockets or housings 0 the plate or piece E with which one end of the bar-h older has a slotted connection, and which is pivoted to one of said boxes 0 at a, a detachable connection between the other end of said bar-holder and the other box (J, and the bar E, adjustable in the pockets or housings 1 0 all substantially as herein described.

5. The combination, with the under cutterhead, its boxes, and the side frames, of an end girth pivoted at one end to swing outward, a bar-holder also pivoted at one end to swing outward independently of the girth, and a bar or mouth-piece carried by the swinging bar-holder, and also independent of the girth, substantially as herein described.

6. The combination, with the under cutterhead, its boxes, and the side frames, of a barholder pivoted at one end to swing outward, and carrying a bar or mouth-piece, a girth independent of the bar or mouth-piece, and a top platen or presser hinged at one end to swing upward and outward, substantially as herein described.

I 7. The combination, with the under cutterhead, its boxes, and the side frames, of an end girth pivoted a t one end to swing outward, a bar 5 or mouth piece supported by the cuttenhead boxes and independently of the girth, and a top platen or presser hinged at one end to swing upward and outward, substantially s herein described.

8. The combination, with the under cutterhead, its boxes, and the side frames, of an end girth pivoted at one end to swing outward, a bar-holder, also pivoted at one end to swing outward independently of the girth, a bar or mouth-piece carried by said bar-holder inde- ,pendently of the girth, and a top platen or presser hinged at one end to swing upward and outward, substantially as herein described.
